【Zookeeper】what is Zookeeper?

官网地址:https://zookeeper.apache.org/https://zookeeper.apache.org/

以下来自官网的介绍

ZooKeeper is a centralized service for maintaining configuration information, naming, providing distributed synchronization, and providing group services. All of these kinds of services are used in some form or another by distributed applications. Each time they are implemented there is a lot of work that goes into fixing the bugs and race conditions that are inevitable. Because of the difficulty of implementing these kinds of services, applications initially usually skimp on them, which make them brittle in the presence of change and difficult to manage. Even when done correctly, different implementations of these services lead to management complexity when the applications are deployed.

所有这些类型的服务都以某种形式被分布式应用程序所使用
Each time they are implemented there is a lot of work that goes into fixing the bugs and race conditions that are inevitable.

每次实现这些服务时,都需要做大量的工作来修复不可避免的错误和竞态条件。
Because of the difficulty of implementing these kinds of services, applications initially usually skimp on them, which make them brittle in the presence of change and difficult to manage.

由于实现这些服务的难度很大,应用程序通常会在这方面偷工减料,这使得它们在发生变更

时变得脆弱且难。
Even when done correctly, different implementations of these services lead to management complexity when the applications are deployed.

即使正确实现了这些服务,当应用程序部署时,这些服务的不同实现也会导致管理上的复杂性。
